Template:Fight InfoboxThe Representative Battle of the Rainbow is a battle between the representatives of all seven Arcobaleno. The Arcobaleno whose representative wins the battle is granted release from their Arcobaleno curse, their baby bodies; or, in the Sky Arcobaleno's case, the removal of the curse of their short lifespan. The planner of this battle is Yonomichi, as claimed by himself, although he also refers to himself as Checker Face's messenger.
Since the seven Arcobaleno are most gifted in their own field and not all are battle-oriented, a rule has been put in place by Checker Face to pick representatives to fight in their place, as if the Arcobaleno Pacifiers were destroyed, it would be disastrous. Each of the Arcobaleno representatives are considered a team; each team is given a box that contains 8 wristwatches. 1 wristwatch is for the Arcobaleno, 1 is for the representative boss, and the 6 others are for the other representatives. The battle taking place would be a battle royale; the team whose boss's watch is destroyed loses. Alliances between teams may be formed. The Arcobaleno of the team, while he or she is allowed to observe, is prohibited from entering and engaging in the battle. If a representative is in serious danger, the Arcobaleno may call into their wristwatch "present, please." This will temporarily remove the Arcobaleno's curse for 3 minutes and allow them to fight in the battle. The Arcobaleno can also manually remove their un-cursed form by saying "present, stop."

Checker Face gathers all the Arcobaleno (sans Aria) in a dream to announce a battle between the Arcobaleno, where their selected representatives fight for them, and the winner's Arcobaleno curse is removed. As a result, all the Arcobaleno find their own representatives except Fon, who had yet to find one. Aria also gives up her right for her curse to be removed, instead giving it to her daughter Yuni from ten years later. Later, when Tsuna and Dino are forced into the Varia's hotel room, a mysterious man with a similar hat to Checker Face's named Yonomichi bursts in the room and announces his status as the planner of the Arcobaleno battle, also explaining the rules of the battle. Yonomichi, after informing the Varia and Tsuna and Dino of the rules, left to inform all of the other representatives of the battle's rules; in Fon's case, he simply told Fon himself, who reassured his pet Lichi that he had found a suitable representative. Before the battle, some teams move to make alliances. Verde creates supposed "new-generation weapons" while Mammon spends his entire fortune to pay Talbot for new Varia Rings.
Enma and some Varia members fight; Skull later on is permitted to join the fray when he utters the words "present, please", temporarily removing his Arcobaleno curse as well. Skull protects Enma from a devastating attack. The result is a draw.
Tsuna and his dad Iemitsu fight. Iemitsu defeats Tsuna. Reborn and Dino meet Iemitsu and negotiate and form an alliance between Team Reborn and Team Colonnello; because of this alliance, Iemitsu does not destroy Tsuna's boss watch.
Fon's sole representative is revealed to be Hibari. Hibari fights against Gokudera, Yamamoto, and Ryohei. Ryohei's watch is soon destroyed, resulting in his elimination. Gokudera uses his new Vongola Gear technique, Zero Ignite, and Yamamoto takes advantage of Kojirou's Rain Flames' Tranquility characteristic to immobilize Hibari, allowing the two to escape, resulting in a tie match.
Team Verde vs. Team Yuni vs. Team Colonnello
During day 1, a single three-way off-screen battle occurred off-screen. It was a battle involving Team Verde, Team Yuni, and Team Colonnello, all pitted against each other. Team Verde managed to defeat Tazaru, Torikabuto, and Daisy of Team Yuni and Turmeric and Oregano of Team Colonnello, although M.M. was defeated in the process.
Team Yuni and Team Reborn fight Team Verde and Team Colonnello (who are not allies). Team Yuni has been eliminated with the destruction of their boss, Byakuran's, boss watch, Team Verde has retreated, and Team Reborn and Colonnello's two bosses' battle was tied.
Team Fon fights Team Mammon, with Dino intervening at a crucial moment and saving Team Fon from elimination. Team Fon eliminated four of Team Mammon's representatives, but when Hibari is enraged that the end of the second day of battle forbade him from fighting Xanxus until the end, he shatters his own Boss Watch, eliminating himself despite the battle having already ended.
Team Bermuda vs. Team Skull
No one challenged Team Skull until shortly before the end of the second day of battle, but suddenly 8 Vindice turn up at the end of the second day, defeats all of Team Skull's members, and forcibly takes the team's Rainbow Wristwatches for entry as Team Bermuda; an action approved by Checker Face himself.
Team Bermuda Surprise Attack
Team Reborn and Team Verde fights Team Bermuda and wins. After Tsuna defeated Jaque, Bemuda wants to invite Reborn onto the team. Reborn rejects the offer. Bermuda created a warp hole and sucked Reborn with Tsuna too because Tsuna wanted to save Reborn.
